The ideal time for pruning roses is the end of winter or the beginning of spring. The pruning depends on the kind of the rose bush. Different rose species need different bush formation. Besides, the purpose of growing roses needs to be considered. What is a rose grown for cutting or plentiful blossoming on the bush?
A gardener pursues three goals when pruning roses.
1. Correct the bush shape after the previous vegetative period. Old branches of the rose bush grew in the undesirable direction. To improve the situation, pruning of the branches is conducted.Pruning recovers the perfect shape of the bushes.
2. Pruning of bushes is performed according to the gardener’s intention:
a) bushes will produce large single flowers on long peduncles.
b) bushes will produce many flowers on many sprouts. In this case, flowers will be smaller but in a big quantity.
3. To renew bushes, pruning old branches and urging bushes to produce new young sprouts.
The most suitable time to prune is when night frost is over, and the buds have not opened yet..
First, examine roses thoroughly. All the branches, which have grown inside the bushes, need to be removed. It will help to thin the bushes of roses out and give them a possibility of better ventilation. Then, damaged or died branches need to be removed. Very tall bushes undergo pruning of all sickly sprouts. If a bush is weak, such sprouts are not pruned but the branch is shortened at least for one bud plant. This will stimulate the increase and strengthen the plant itself. Pruning roses should be performed so that the existing roots would be able to feed all the branches of the bush over ground part. This is an important pruning condition. In this case, roses will grow the sprouts normally and bloom well.
Pruning Roses for Growing Large Flowers
Besides pruning roses with large flowers for the sanitary purposes, they are pruned to grow big flowers for cutting. In this case, on every branch you have left the sprout should be pruned so that 3-4 pieces of bud plant on it are remained. This promotes the development of strong sprouts from a small quantity of buds. On such long sprouts large flowers are developed.
Pruning Roses for Growing Flowers in the Flower Bed
If you want roses to bloom plentifully in the flowerbed, pruning should be performed so that the sprouts, remaining after the preliminary pruning, still have 3-6 pieces of bud plant for the growth. As a result of such pruning, a lot of flowers will appear.
Pruning of Floridunda Kind of Roses or Hybrid Tea Roses for Growing in a Flower Bed
If you want to create a thick bush of these species, you need to conduct formative pruning. Perform pruning depending on how you imagine this bush in the future. First, conduct sanitary pruning and then start shaping of the bush. It is hard to say how many pieces of bud plant have to be left. The number can be 3 or 6. Everything depends on the bush that you have decided to form. If the blooming and growth of such bushes lowers, pruning roses heavily may be required in future.
Pruning of Tiny Roses
In general, small bushes of roses are pruned the same way as bushes of hybrid tea roses. There is sanitary and formative pruning. 2-3 pieces of bud plant are left on the branches. The length of the branch should not be more than 4″ (10cm). If you do not prune the plant, it will enter the stage of blossoming much later. In summer the flowers, which have shed their blossoms, are removed, as well as dry twigs and withered leaves. This is done to prevent appearance of pests and diseases on them and to improve the charm.
Pruning of Curly Roses
Spring pruning of curly roses is done only at the ends of the branches. If the plant is older than 4 years, old sprouts are pruned completely after blooming is over. Young sprouts are not pruned during the year, because roses will bloom exactly at their endsnext year.
Pruning Roses Tips
1. Early and timely pruning stimulates blooming. If pruning is carried out too early, before light frosts are over, it will slow blooming of roses.
2. Pruning roses too late slows the beginning of vegetation.
3. Fertilize rose bushes after pruning.
4. To stimulate growth of the bud plan on curly roses tie up a young branch in a horizontal or slanting position.
Such kinds of roses as R. Spinosissima, r. Rugosa, R. Gallica and their hybrids, r. Moschata usually do not need pruning at all. Flowers appear on side branches of 2-year old sprouts and old branches. Pruning roses is done in case if branches damage or their natural dying off.
The best instrument to use for pruning is a knife in order not to crease branches. A knife for pruning roses should be sharp. Disinfect it before pruning.
Pruning is done 5-8 mm above the bud plan to prevent the future sprout from drying. The cut should be done slantwise from the bud plan.
